Q.

The product of two successive numbers is 8372. Which is the smaller between these two numbers?

[A] 75
[B] 64
[C] 91
[D] 82
Answer & Explanation
Option: [C]

Let the two numbers be x and (x+1) respectively

So, x(x+1) = 8372

x2 + x - 8372 = 0

x2 + 92x - 91x -8372 = 0

(x + 92)(x - 91) = 0

x = 91

Hence the two numbers are 92 and 91 and the smaller number is 91
